MACHINE FOR CRIBB'ING CORN.

SPECIFICATION forming` part of Letters Patent No. 517,355, dated March 27, 1894.

Application filed May 5,1893. Serial No. 473,157. (No model.)

To all whom it may concern,.- r

Be it known that I, LODRICK M. MILLEN, a citizen of the United States, residing at Elwood, in the county of Gosper and State of Nebraska, have invented a new and useful Machine for CribbingCorn, of which the following is a specification.

My invention has for its object the production of aportable machine designed to be arranged alongside a corn-,crib and to receive and elevate ear-corn to the crib; to construct the machine in a cheap and simple manner and so as to expedite the cribbing of the corn; and to provide for an automatic dumping, whereby the necessity of several operators or attendants for the purpose of operating the machine is avoided.

Various other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointedout in the claims.

Referring to the drawings-Figure 1 is a perspective view of a machine constructed in accordance with my invention. Fig. 2 is a vertical transverse sectional view through the tower and cage or car. sectional view through vthedrive-way illustrating the wagon dumping-mechanism. Fig. 4 is a vertical longitudinal sectional view.

Like numerals of reference indicate like parts in all the figures of the drawings.

It will be understood that the construction v of the frame and arrangement of the timbers for the support of the machine maybechanged at will, as may also other details of construction not necessary to specifically mention;

and I would'therefore state at the beginning of the specification that I do not limit my invention to such precise arrangement of details as I herein show and describe, but hold that I may vary the lsame to any degree and extent within the knowledge of the skilled mechanic. For the purpose,however, of illus-A n tration, I will 'proceed to describe a simple form of framework which I'consider` as best.

' adapted to the circumstances of the case.

1,-1 designate a pair of opposite longitudif nal parallel base-sills of suitable length, by Which'is meant a length considerably longer than a wagon` andy team of horses, and at pointsat each side of the centerthereof I arrange short vertical studding 2, connecting Fig. 3 is a transverser the same by means of upper sills 3,1ongitudinally arranged, and in turn supporting above the studs transverse sleepers 4. Supported by the sleepers A are floor-beams 5, and similar beams 6 decline from the outer or endsleepers 4 to the outer 'ends of the sills l. The licor-beams 5 and 6 vsupport an ordinary door 7, and at the opposite sides thereof a guard or handral 8 is located. The two sleepers 4 at one end of the framework have located intermediate the door-beams 5 two pairs of longitudinal beams 9, the beams of each pair being arranged a slight distance apart, and pivoted between their ends between these pairs of beams 9, as indicated at 10, is a pair of levers l2, whose outer ends are connected by'a transverse platform 13.-

A pair of transversely opposite bearings 14 are located in the under sides ofthe upper sills 3, immediately in rear of the rear or inner -ends of the levers l2, which I will term dumping-levers. These bearings have journaled therein a transverse rock-shaft 15,

and from said rock-shaft extends a pair of short beveled rock-arms 16, which, when the levers l2 are elevated, take under the free ends of the same and support saidrlevers in positiontlush with thek drive-'way or floor '7. The rock-shaft, however, may be oscillated so that its rock-arms 16 are withdrawn from their supportingv position under the levers l2, whereupon said levers 12 are capableof being depressed at their rear or inner ends belowk the plane of the oor'or drive-way. For the purpose of accomplishing such unlocking of the lovers I provide the rock-shaft with an operating rock-arm 17, and extend from the free end of the same up through a perforation in theoor an operating-rope 18 terminating in a suitable hand-hold or loop.

Arranging the two driveways at opposite sides of an intermediate point of the framework, it will be seen that a space occurs between the inner ends of said ways, which space is rectangular in plan, and lI .support 'upon the sills 1 at the four corners ofthe space the four posts 19 lof a vertical tower. The `posts '19 are connected at their upper ends by a suitable framing ofordinary construction, and from the central portion thereof there depends a sheaveQO, through'which p an elevator rope 2l passes, the same also pass IOO l ing through a lower sheave 2l', which is provided at its lower end with a hook 122. The rope 2l passes over suitable guide pulleys 23 located in the tower and on the Hoor or drive- Way, and finally terminates in a hook 24 designed to be engaged with the axle or other part of the running gear of a wagon, said rope and its adj uncts constituting a fall.

25 designates a car, which is located for vertical movement in the tower, and said car is provided at its four corners with angular re cesses for loosely embracing the posts 19 of the tower. The car has pivoted at one end by a rod 2G, a swinging bottom27," the `same having opposite side-walls adapted to close within the side-walls of the car. Theposition of the bottom .pivot-rod .26 may be changed from that shown, that is, remployed for; pivoting the opposite end of the bottom in` position, so that the ear is capable of `dumping at either side, `and for such purpose `the catch-mechanism together with the devices-` forreleasing the same are duplicated at each side otythecar. The ends of the bottom are provided `with pinsV 28, and the ends of the car` havesecuredthereto spring-catches 2.9,twhose` lower Yor shouldered ends -30 `are beveled solas toride over thepins `28 before engag-` ingrthe same. Levers 3l are pivoted as at 32 totheends off the cartand have their .upperi ends outwardly bentas at33. A limiting` bail of inverted U-shapeand .designated-tas 3,4 is secured to the upper edges ofthe sides of `the bottom, and at its upper corners is reversely bent las at to formstopsgwllerer by the drop of the `bottom `is limited `by reasontof thestops contacting with the upper edgesof thesides of the car. A bracketframe 36 extends outward from the opposite sidesofrtheftower iandintolthe path `of the lateratprojection or bent end of the lever 3l, so .thattwhenl` the carhas reached a sufficient elevatiolrthe upper bent end of thelever 31 contactingywith the bracket will cause said` lever to oscillate,andinasmnch as the latter bears atiitslower end `against the-springcatch, said spring-catch will be forced toene` fside against itsown tendency and from underithe pin 28 ot the bottom of the car, therebyipermittingsaid `bottom to drop and the contents ot the car to be discharged tromone; side thereof.. Asbefore stated, by the dupli` cationtefthis mechanism atthe opposite side ofl the car and` antinterchanging of the pivotpin of thelbottomfrom onesideof the car to the other, the `car -is-adapted to deliver `at eitherside thereof.

"lhctop of thecar, whichformsa continuA ation of thedriveway when the cariis in .its lowered tposition, is .f provided with anopening Q39, and thesame is covered bya doen/l0.` At onetside of the door, or, in otherlwords,w at the center of the car a ring 4l isilocated, the; same being designed to beengaged remov` ably by` the hook 22 of the lower-sheave `1er pulleyebloclr. l

This completes the construction of the de` vice, with the exceptiomof suitable transporting rollersftZwith which the sills 1 are provided. These rollers are preferably mounted upon bell crank levers 43, which are pivoted at their angles to the sills and are designed to be so manipulated as to depress the rollers andthus elevate the structure and support it thereon, or` to elevate the rollers and lower the structure so that the latter rests solidly upon the sills. In either ot' their positions the upper bent ends of the levers act as stops by contacting with the upper edges of the sills so the rollers are supported either above or below the lower edges of the sills. When the rollers are depressed and the structure elevated, transportation is rendered easy, as will be obvious.

:The car heilig loweredtoiposition uponthe sills l, ateam for hauling the `.eorinis driven up the incline ofthe drivewayoppositeto that portionthereof in whiclnthe `dunciping levers are located, andyzcrossingthe` car,.con tinues its travehuutillthe hind-wheels of the wagon rcstupont-the rear endslofithe` dumpin g-levers12., `The trap-doorotthe car is now openedand the operator grasping .the uope 18 draws the `sanne npward,thus:withdrawing the'rockarms 16 from undertherear:endsfof the dumping levers andpermitti ngthe wagon to `tilt `or dumpyits :conteutsjalling from thence through the opening in' the `car i "and into the latter.
